I ordered 3 sets of drawers and sleeves. On all 3 sets the sleeve is a good inch larger (taller) than the drawer, making it unstable for stacking. It seems as though the correct size drawer was bundled with the wrong size sleeve at the factory. Unfortunately we didn't need the boxes immediately after they were ordered and now the office supply store will not take them back even though they are faulty. I came to the website hoping to find customer support contact info but since there is none, my only recourse seems to be to leave a bad review.
